I want to run a mysql query including variables. A simple version of this looks like that:
$sql = "UPDATE mytable,
(SELECT @counter := IFNULL(@counter,0) + 1 as new_value,
mycolumn
FROM othertable
ORDER BY mycolumn) i
SET mytable.counter_column = i.new_value
WHERE i.mycolumn = mytable.mycolumn";
$this
->getSlaveSql()
->getAdapter()
->getDriver()->getConnection()->execute($sql);
But the result value is always 1. If I run the query directly, I have a correct line of numbers. I think, the variables will be unset bei Zend, so that @counter is 0 on every row.
